INSULATED RAIL-J 01N T.

Application tiled January 13, 1908.

To all whom it may concern.'

Be it known that I,REUBEN W. SMITH, a citizen of the United States,residing at Marietta, in the county of Lancaster and StateofPennsylvania, have invented certain new and useful Improvements inInsulated Rail- Joints, of which the following is a specification.

This invention relates to rail joints of the insulated type, and hasspecial reference to a novel and practical joint of this'charactercomprising means for providing a .solid metallic bearing 'support attheunder sides of the rail heads, and also maintainin a complete andeffective insulation throng out the entire joint.

As a general object, the invention has in View a construction wherein noinsulation is interposed between the heads of the rails and the metallicbars next to the same. This admits the heads of the 'rails taking a4solid and direct bearing on the -joint bars, while also .permitting ofsuch a dis osition of the insulating material as to re ieve the samefrom the pressure of the load without detracting at all from theefficiency ofthe insulation. In other words, the invention provides' astructure in.which a solid metallic bearing is secured for the railheads, anda complete insulation of the joint is effected by anarrangement of insulation upon which practically no fiber strain isimposed..

With these and many other desirable `objects in view which will`readilyappearto those familiar withthe-.art as the nature of ,A theinvention is better undertood, the same consists in tliejnovelconstructiomcombination, and arrangement of parts hereinafter more fullydescribed, illustrated and claimed.

The essential features of the invention are susceptible to embodiment indiferent'kinds of structures and in dierent ways without affecting thescope. of the invention, but a preferred embodiment of the latter isshown in the accompanying drawings, in which: l

. A rail joint constructed according to t e design and plan ofthepresent invention embodies in its organization the service rails R,the side joint bars l, and the usual series' of joint bolts 2. Thesejoint bolts are l-tted with any of the approved bolt insulating cxpedients 3 such as usually resorted to for 1nsulating the bolts fromthe joint bars, b ut the characterizing feature of the present 1nventionresides in the employment of joint bars having a direct metallic bearingwith the rails, and which bars are discontinuous, that is termi-nate ator near the meeting ends of the rails, and therefore do .not extendcontinuously throughout the jointas do the ordinary angle bars or`splice bars commonly employed in rail joint structures both of the'standard and insulated types., It will therefore be observed that thejoint is provided `withwhat may be termed two-part or d1- vided jointbars, so that there are separate joint bars or joint barsections foreach rail,'

the same being arranged respectively upon v 'opposite sides of the'rails and tho-roughly insulated from one another in a manner to bepresently explained. A

As indicated,` the separate joint bars for each rail are oflengthsapproximately equaling one-half thelengtli-'of the joint so as toterminate at or near thejoint between the meeting ends of the rails, andin the carrying out of the invention-these separate joint bars may be ofany conventional or approved design according to the type of rail jointto' inthe lillustrated.embodiment o'f the-invenj tion, each joint barconsists of'the'- main 'upright section or'girder 4 formed at its upperedge with the usual' thickened bearing head 5 having a direct metallicbearing against edge the upright sectionfor girder 4 of each angle bar lhas formed integrally therewith .anouttu1ned foot flange 6 overlying;the rail flan-ge and formed with an inclined bearingv face 7 ha1vingdirectmetalliccontact with the inclinedupper face'of fia-nge.
